Abstract

Aim: Vitamin D is effective in calcium absorbtion and bone metabolism. Also, decreased vitamin D levels are associated with most of the chronic diseases such as DM, HT, cancer and otoimmune diseases. In this study, we aimed to investigate vitamin D levels that is carried out in our laboratory between January and December in 2012. Materials and Methods: A total of 4168 patients between January and December in 2012 were evaluated and age, sex and vitamin D levels classified by month. Results: In our study, 3242 (77,8 %) female and 926 (22,2 %) male were included. Mean vitamin D levels were 22,80±13,27 ng/mL, 22,49±13,88 ng/mL in female patients, 23,75±10,57 ng/mL in male patients. 47 % of patients (50 % in female 38 % in male) have vitamin D levels under < 20 ng/mL (cut-off for vitamin D defiency). Conclusion: Our results showed that there was an important difference between vitamin D levels when patients compared according to sex, age and months. These variations may be important in clinical desicion because vitamin D levels were evaulated according to defiency cut-off and this cut-off is not different for sex and seasons.

Özet

Amaç: D vitamini, kalsiyum absorbsiyonu ve kemik metabolizmasında etkilidir. Ayrıca düşük D vitamini düzeyleri DM, HT, kanser ve otoimmun hastalıkların yer aldığı çoğu kronik hastalık ile de ilişkilidir. Bu çalışmada laboratuvarımızda 2012 yılı Ocak-Aralık ayları arasında çalışılan D vitamini düzeylerinin incelenmesi amaçlandı. Materyal ve Metod: 2012 yılında Ocak-Aralık ayları arasındaki 4168 hasta değerlendirildi ve yaş, cinsiyet ve D vitamini düzeyleri aylara göre gruplara ayrıldı. Bulgular: Çalışmamızda 3242 (% 77,8) kadın ve 926 (%22,2) erkek yer aldı. Hastaların D vitamini düzeyleri ortalaması 22,80±13,27 ng/mL, kadınlarda 22,49±13,88 ng/mL, erkeklerde 23,75±10,57 ng/mL idi. Hastaların % 47’inde (kadınlarda % 50, erkeklerde %38) < 20 ng/mL D vitamini seviyeleri vardı (D vitamin yetersizliği için cut-off). D vitamini yetersizliğinde mevsimsel değişiklikleri incelemek için ortalama D vitamini düzeyleri karşılaştırıldığında tüm gruplar arasında istatiksel olarak anlamlı fark bulundu ( p<0,001). Sonuç: Bizim sonuçlarımız, hastalar cinsiyet, yaş ve aylara göre karşılaştırıldığında, D vitamini düzeyleri arasında önemli bir fark olduğunu göstermiştir. Bu varyasyonlar klinik kararda önemli olabilir çünkü D vitamini düzeyleri cut-off’a göre değerlendirilmektedir ve bu cut-off cinsiyet ve mevsim açısından farklı değildir.
